The firmware would not have done you much good because he was using a PIC processor and not an AVR processor like the Arduino. He did a good job of explaining how he analyzed the signal and determined the format. You just have to reproduce his work. You can use the pulseIn() function to measure input pulses in microseconds. It looks like each bit is represented by two pulses: short-short for 0 and long-long for 1. A pattern of short-long pairs seem to signal the beginning of data. Hook up your radio and measure 100 pulses. Look for patterns. Once you determine the length of a 'short' pulse and a 'long' pulse you can use those values to ignore noise pulses. Then you can start looking for the data patterns: some unknown number of short-long pairs followed by some fixed number of short-short and long-long pairs.
